What's wrong with receiving a free courier bracelet for no reason?

Receiving a free postal courier bracelet for no reason may be the following situations:

1. Common business promotion activities: Some businesses will promote their brands or products by giving away items for free to attract potential customers or enhance brand awareness. In this case, receiving a free courier bracelet may be a marketing tool.

2. Mismailing or fraud: Sometimes, it may happen, such as accidentally filling in someone else's address, or criminals using free items for fraud. In this case, it is recommended not to sign or accept items of unknown origin easily to avoid losses.

3. Lottery or competition activities: Some activities may give prizes in the form of lottery or competition. If you have participated in similar activities, receiving a free postal express bracelet may be a proof of winning the prize or a gift.

In either case, if you are not sure about the source and authenticity of the free postal express bracelet, it is recommended to consult the postal party or relevant institutions first to avoid possible risks and losses. At the same time, it is best to have professionals present when disassembling the express delivery to ensure safety.
